[Ord. No. 2010-1621 §1, 4-20-2010]
The purpose of this Article is to supplement regulations and standards established in this Chapter to effectively mitigate soil erosion, sedimentation and stormwater (collectively "surface water") runoff during and following any land disturbance including grading, building and landscaping.
[Ord. No. 2010-1621 §1, 4-20-2010]
Any application for a building, demolition or grading permit which would result in the following shall be accompanied with a erosion, sedimentation and stormwater control plan:
A decrease in the permeable surface of a lot, or
An alteration to the existing grade or elevation of a lot, or
A change in the existing flow in terms of location, direction, rate or volume of surface water from a lot shall be accompanied by detailed plans and calculations identifying and comparing pre-construction grading and post-construction grading relative to erosion, sedimentation track out, stormwater runoff and grade/elevation conditions.
The City may require the following to be include in this plan if not otherwise required elsewhere in this Chapter:
Proposed dates, timing and sequencing of the project including installation of sediment controls, clearing, rough grading, construction, paving, final grading and landscaping.
Effective control of surface water runoff to ensure soil and sediment is contained on the site during any land disturbance or other development activities and after any such development activities, including details of any temporary drainage or impoundment systems.
Measures to be taken to control sediment track out onto roadways and adjacent property including temporary access routes.
Existing and proposed topography of the development site including existing and proposed direction of runoff flow.
Calculations showing the percentage of existing and proposed impervious surface relative to the entire site.
Calculations showing existing and proposed final peak discharge rates.
Drawing(s) indicating all proposed stormwater runoff facilities and their tie-in to existing stormwater drainage routes.
Landscape plans indicating soil preparation and revegetation methods.
The name(s), addressee(s) and telephone number(s) of the engineering firm(s) and registered professional engineer(s) who designed the documents.
The name, address and telephone number of the property owner.
Other drawings or specifications reasonably required by the City to assess stormwater runoff and to assure that stormwater will be collected, retained, detained or otherwise controlled so as not to increase runoff onto any adjacent properties or public improvements or rights-of-way.
Approval from the Metropolitan St. Louis Sewer District ("MSD") and the Department of Natural Resources (MDNR) when applicable and, if the subject property is located in a subdivision, consent of the subdivision trustees, if applicable.
[Ord. No. 2010-1621 §1, 4-20-2010]
No land disturbing, construction or other associated activities shall be permitted to deposit mud, soil, earth, sand, gravel, rock, stone, concrete, building or other materials on streets and/or adjoining property. Trucks and other construction equipment shall be cleaned on site to prevent mud from being tracked onto any street.
If mud, material or debris is deposited on any street and/or adjoining property, the general contractor, developer or owner responsible for the development site concerned shall be notified and shall abate the violation within four (4) hours of notification.
Notification may be made by telephone, fax, personal contact or site posting. The notice will include the time notified and deadline for abating the violation.
If the violation is not abated within four (4) hours, the City will cause the violation to be abated at the property owner's expense. The escrow or bond posted pursuant to the building regulations of the Code of Ordinances of the City of Frontenac shall be used to satisfy the cost of abating any violation of this Section, with any excess costs beyond proceeds and recoveries from the bond to be paid to the City by the property owner.
